Discovery centre, 3rd floor Oishii Grand, 1k baht ($40) per person, yes its a bit expensive, but you'll get to eat many varieties of Japanese food. I spent 4 hours there until my stomach bloated.
Pat Phong along the street, there's this red signage restaurant selling Japanese Yakiniku, you wont miss it 1, quite nice also.
Sorry, no eat thai food there, too sweet for my liking. But i went to Siam Square, there is this thai restaurant, white building, very famous for tourist. Not expensive lah, still ok. This is the website.
